What are my chances?

I have pcos since i was 17. Im now almost 21. I just cant seem to get pregnant. I was on birth control when i was 15 & one day i just wanted to stop takin them and i bled for a month straight.. i was in the hospital because of that. I was put on metformin when i was 17 for my weight then stopped.

I thought i concieved twice because i thought i miscarried because of the way i felt. I could be wrong who knows.. but anyways now im on hydroxycut gummies to loose weight and prenatal pills... we pray every night for a child.

But its just not happening... any ideas or natural remdies.. i do not have insurance and no money for a doctor.. so appointments and doctors are kut of the question.
